Additional cost for shower on the ground floor (guest WC)

Hello everyone,

does anyone have experience with the surcharges to be expected for a shower in the guest bathroom in turnkey construction?

Assumptions:

[*]Additional costs for planning layout changes are not considered; starting size of the guest bathroom: 3 sqm

[*]Simple equipment standard (no walk-in shower, mid-range fittings)
[*]No additional towel heater (only the existing underfloor heating; the shower is meant to serve the purpose: quick in, quick dry off, quick out)

Thanks for your feedback.

We were quoted an additional cost of €1200. However, this means giving up one square meter in the utility room...

We paid a similar surcharge as Häusle77 for the floor-level shower in the EG guest bathroom. I think this certainly varies depending on the provider.

The order of magnitude of 1200 euros was also offered to us by 3 BU. That’s about right.

One should know: if the BT/GÜ or the BU wants 3000, then you can't change that just because others only want this 1200 ;) At least you have a reference value.
